Non‐Destructive Inspection of TCPs Using Pulse‐Echo Ultrasound and X‐Ray Microcomputed Tomography Techniques

X-Ray Spectrometry, EarlyView.
ABSTRACT Thermoplastic composite pipes (TCPs) have potential applications in offshore oil and gas industries because of their strength, lack of corrosion, and flexibility. Designed for fluid transportation in high‐pressure and high‐temperature environments, manufacturing defects and operational loads can compromise their performance.

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

The FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...
